186953-23-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 186953-23-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,9,5 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 186953-23:
(8*1)+(7*8)+(6*6)+(5*9)+(4*5)+(3*3)+(2*2)+(1*3)=181
181 % 10 = 1
So 186953-23-1 is a valid CAS Registry Number.

An efficient total synthesis of (2E,4E,7R)-farnesa-2,4,10-triene from (R)-(+)-citronellal

Li, Jing,Liu, Zuosheng,Lan, Jiong,Li, Yulin

, p. 259 - 262 (1999)

(2E,4E,7R)-farnesa-2,4,10-triene(Caparratriene) (1), a novel sesquiterpene hydrocarbon with significant growth inhibitory activity against CEM leukemia cells, was first synthesized from (R)-(+)-citronellal (2) by employing titanium-induced intermolecular

The formal total synthesis of FR252921-An immunosuppressant

Yadav,Sengupta, Sandip

, p. 376 - 388 (2013/03/13)

The formal total synthesis of FR252921 is described. The key steps include the preparation of three fragments starting from 1,4-butanediol, (R)-malic acid, and prenol, respectively, followed by two consecutive peptide couplings of the three fragments. Other key steps involve an allene-type rearrangement or enyne isomerization to install the triene moiety, a Seebach methylation, a Julia olefination to construct the trisubstituted diene unit, and an enzymatic resolution strategy to generate the C-18 stereocenter.

Intramolecular Formal oxa-[3 + 3] Cycloaddition Approach to the ABD System of Phomactin A

Cole, Kevin P.,Hsung, Richard P.

, p. 4843 - 4846 (2007/10/03)

(Equation Presented) The ABD-ring of phomactin A was synthesized using an intramolecular formal oxa-[3 + 3] cycloaddion of an α,β-unsaturated iminium salt tethered to a 1,3-diketone. This represents the first time that the 12-membered ring has been formed
